Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1893 edition. Excerpt: ...This invention relates to improvements on the invention described in specification No. 3238 (1871). The machine is placed at a suitable angle to the horizontal, and the fixed aeroplanes at the hinder part of the machine, supporting part of the weight, reduce the angle of flight as the speed of the machine increases. The pendulum adjusts the revolving aeroplanes, and steering may be effected by altering the angles of the aeroplanes while in motion. The machine can be mounted on pontoons or wheels, to adapt them for resting on water or land when at rest. A pendulum regulates steam or other valves, which actuate mechanism for regulating the angle of a balancing plane, which latter keeps the machine at the desired angle. (Drawing.) A.D. 1874. No. 2821. BAGGS, Isham. Provisional only.) "Balloons." Hydrogen is generated in suitable generators, by the action of hydrochloric acid or zinc. In inflating fire-balloons the products of combustion are caused to pass through layers of wire gauze. Wings are attached to a framework surrounding the balloon, which wings being inclined at an angle cause the balloon to travel on an incline when rising or falling. These wings are so balanced that they take the required angle by the pressure of the air up or down. A tail is employed for steering. An arrow is shot into soft ground to anchor the balloon when landing. A.D. 1874. No. 3058. LAKE, William Robert. (Communicated by William Frank Browne.) "Hydrogen Apparatus." A Portable hydrogen generator is described in which steam is passed through retorts over incandescent material, and from thence through a condensing-coil. (Drawing.) A.D. 1874. No. 3132.
